To all whom t may concern: Be it known that I, FRANK S. INGOLDSBY, acitizen of the UnitedStates, residing at St. Louis, in the State of and useful Improvement in Dump-Cars, of which the following clear, and exact description, reference being ings.

This invention is particularly adaptable for cars of the Ingoldsby type, wherein there is a. central longitudinal beam, to the-oppodoors adapted toswing downward toy discharge the load.`

The invention is concerned with the structure of such beam Aand the door -raising mech-anism carried thereby.'

It may be summarized as consisting of the features of construction shown in the drawings hereof and herein described and.

l,set forth in the claims.

In the drawings, Ficure l is a cross section. through an Ingoldsby dumpca-r. embodying the present invention. Fig. 2 is a ysectional plan on the line 2 2 of Fig. l. Fig. 3 is a longitudinal section of the4 car. Figs. 4 and 5 are end views,-F ig. 4L being from the outside, and Fig. 5 on the line 5-5 of Fig. 3.

The central longitudinal beam of the car is' a double truss or box girder structure comprising an upper chord A, which is a metal plate of inverted V-shape, lower chords' ory bracing members, shown as channel beams BeB, and vertical plates C-C riveted to the channel beams andto the ridge -plate A. Vhere'these plates C engage the ridge plate they are bent inward and lie along'the ridge plate, thus roviding more metal for the upper chord.) This. upper chord is still further reinforced by an angle iron D running lengthwise beneaththe ridge plate A. The upper ends of the plates C and this angle D are all securely riveted together. At the lower edge of this double girder are'icross braces E, whichif desired may be' formed by lattice, a plate or separate braces. v This longitudinal beam extends to the bolster to which its upper and lower chords and vertical plates are secured, as

shown in Fig. 3, where I represents the tension member and I the compression member' 0f the bolster. The various parts of the center structure pass" through the inclined end Missouri,"have inhad to the accompanying draw` with the ridge plate and compact beam having theA which are pivoted dumpingladdition t-o the advantages around onto itself which engage the ridge edandbent around on themselves to form floor O and lterminate between these members of the bolster. '.Connected to the lower chord of the' box glrder above described at intervals and extending outward therefrom` are plates F. These plates are in pairs on girder and extend out-ward tion of the ridge plate A, being connected with the girder by angle Irons f, f andsuitable rivets. This construction makes a very strong, light and c desired slope for discharging the material. It constitutes one of the features of the present invention. In

of strength, Colnpactness and lightness of the above described c entral beam, itis particularly well adapted for carrying the pivots of the dumping doors and the 'door raising mechanism. ing doors are-indicated by G. They have on their underside floor beams g, in the form of angle irons,-the horizontal iiange of which is extended at the inner end The dumpto form a hinge eye at g. In the same manner the 'iianges of the clips plate are extendhinge eyes f2.' v^Through the three eyes thus presented in alinement passes a hinge bolt H. Pivoted on bolts J which pass through .the plates F and the angle clips f are operating arms K. These arms'are located between suitable p'airs of plates F. Each arm extends outwardlyand is adapted to have its free end' engage the dumping door either on the plate thereof or the angle g beneath the same. These arms K are adapted to be drawn upward by chains L connected with t-he arms at aand passing upward beneath the ridge plate to a common operating shaft N which is carried in bearing blocks I between the vertical plates C and rivetedvor bolted to them.

From the above described mechanism, it results that if the' shaft N" is rotated, the chains are wound thereonto and the arms/cy are drawn upward, raising the dumping doors. Toconveniently rotate the shaft N, I extend it longitudinally beyond the end of the ridge plate and the bolster to which the ridgev plate is secured and connect it by suitable gearing with `a crank R. As shown, the crank has on it a small pinion R which meshes with a large gear S on an intermediate shaft S: On this shaft is each side of the, to the lower porand bent sition with the gears in mesh.

It. releasing and latch mechanism is shown in a pinion S2 meshing with a gear T on the shaft N. The inner end of the shaft S is capableof a slight downward movement to release the gear Sfrom the pinion R so that the crankwill not be thrown violently around when the doors are dumped. A suitable latch U normally holds the shaft vin po- The doors may be locked in closed position or released therefrom by any desired mechanism, and the releasing mechanism may automatically operate the vlatch U to release the shaft S, allowing ii: to drop suiiicientlv to move the ger.'y iw" out of engagement with the pinion A convenient form of such locking,

Patent No. 784:,265 granted March 7th, 1905, on an application with the present inventor and Joseph R. Bowling.

In order to form a suitable stop for the dumping doors when they are dropped, I provide a shoulder /if on the arm K which is adapted to abut the underside of the central beam when the arms are down. The

arms thus form not only the means for rais? Having thus described my invention, I
